Background technology
China more and more adopts mechanized in the rural area at present, and sower is commonly used in a lot of areas.But what present employed precision sower adopted mostly is the individual profiling design, and the seeding mode is front-seat formula, and defertilizing wheel is coaxial with land wheel, and by chain drive, fertilizer is row replacement, can not realize spreading manuer in holes between seed wheel and the land wheel; The miniature seeding machine that has adopts seeding and fertilizing to carry out simultaneously, and fertilizer contacts easily with seed, thereby causes the phenomenon of fertilizer burn seed, influences emergence rate; The adjusting of a lot of sower amount of seed meterings is in kind of case, and some sower regulates amount of seed metering and need regulate each type hole, adjusts very trouble, wastes time and energy, and influences the sowing progress.
Summary of the invention
The purpose of this utility model is to provide a kind of profiling effective, articulates simple plate, the seed manure layering, and discharge capacity is easy to adjust laborsaving, and is simple in structure, back row's formula precision sower with low cost.
The purpose of this utility model is to realize by following technical scheme:
A kind of back row's formula precision sower, comprise the frame that seed-box and fertilizer can are installed, land wheel is installed in this frame back, on the frame of land wheel front, plough is installed, its structural feature is: the profiling quadric chain is installed in said frame front, this profiling quadric chain comprises fixedly V-arrangement fixture block, fixedly the front of V-arrangement fixture block connects a movable V-arrangement fixture block, movable upper connecting rod and the lower link of connecting in said fixedly V-arrangement fixture block back, the other end of said upper connecting rod and lower link connects the fixture block that floats, should on the unsteady fixture block said plough be installed, connect positioning drawing plate on the said unsteady fixture block, limiting plate is arranged above this positioning drawing plate, and a draw-in groove is opened in the centre of this positioning drawing plate.During the utility model work, can by the depth that the profiling quadric chain is regulated trench digging at any time, make the sowing depth unanimity according to surface state; By limiting plate, can limit the depth capacity of trench digging; Facility can lift frame when not working, and block by draw-in groove.
On the said land axle master gear is installed, the land wheel front connects defertilizing wheel axle with the fertilizer gear of this master gear engagement, the land wheel back connects seed shaft with the seeding gear of master gear engagement, and defertilizing wheel and seed wheel are installed respectively on said defertilizing wheel axle and the seed shaft.Because defertilizing wheel is preceding, seed wheel after, the fertilising earlier of plough trench digging back, sowing again behind the soil that falls above the fertilizer.
A support plate is installed in said seeding box back, by bolt the adjustable supporting plate that the other end puts in seed-box is installed on this support plate, and an end that puts in seed-box of this adjustable supporting plate is installed and scraped kind of a tongue.Adjustable supporting plate can put in the length in the seed-box according to the size adjustment of seeding quantity.
Said fertilizer can back is installed one and is regulated the tongue support plate, and this adjusting tongue support plate is installed the adjusting tongue that the other end puts in fertilizer can by bolt.
On the hanging beam of said profiling quadric chain front marker is installed.During mechanical work, marker stays the width of this subjob, grasps when being convenient to subjob down.
Earth separation plate is installed at V-arrangement fixture block place at said profiling quadric chain.
In said frame back press wheel is installed, the press wheel back is rack-mounted trailing bar.
Advantage of the present utility model is: during the utility model work, can by the depth that the profiling quadric chain is regulated trench digging at any time, make the sowing depth unanimity according to surface state, avoid the seedling-growing time difference that causes because of sowing depth is inconsistent, and then avoided shoot-breaking phenomenon; On the profiling quadric chain, limiting plate is installed, can be limited the depth capacity of trench digging; Facility can lift frame when not working, and block by draw-in groove, and are simple to operation, safe and reliable; The utility model defertilizing wheel is preceding, seed wheel after, the fertilising earlier of plough trench digging back, sowing again can be brought into play the effect of fertilizer to greatest extent behind the soil that falls above the fertilizer, can avoid fertilizer burn kind of bud again, and drop on the wet soil with trench digging back seed, earthing again after suppression, the soil moisture conservation performance is good, help seed sprouting, can guarantee emergence rate; Seeding quantity of the present utility model and fertilizing amount are all adjustable, and to regulate be in seed-box and fertilizer can back, regulate more conveniently, and accent amount size is easy to grasp, and regulates as required at any time, and is time saving and energy saving, convenient and practical.The utility model is simple in structure, and is with low cost, and adaptability is strong.
